Physics - Elecrostatics Question with Solution | TestHub

A point charge causes an electric flux of $-2\times 10^4{\mathrm{Nm}}^2{\mathrm{C}}^{-1}$ to pass through a spherical Gaussian surface of 8.0 cm radius, centred on the charge. The value of the point charge is : (Given ${ϵ}_0=8.85\times 10^{-12}{\mathrm{C}}^2{\mathrm{N}}^{-1}{\mathrm{m}}^{-2}$ )
